Percentage chance of a successful attack.

For each attack a unit has, it chooses a random enemy target and "rolls" a 1-100 die.

Any roll under the offense number is a successful hit.

For example, a Mud Wretch, which has an offensive rating of 70, successfully attacks an enemy target if it rolls a number 70 or under;if it rolls anything over 70, it simply misses the target.
